IMPROVEMENT IN BELLOWS.

Specification forming part of Letters Patent No. 217,661, datcd July l5,1879; application Iilcd May 13, 1879.

To all whom it may concer-n:

Be it known that we, ANTON H. WIEsE and JOHANNES E. RODER, ofIndianapolis, in the county of Marion and State of Indiana, haveinvented certain new an d useful Improvements in Bellows, of which thefollowing is a description, reference being had to the accompanyingdrawings.

Our invention relates to certain improvements in the valve-seats, thenozzle-head, and the nozzle of bellows or air-pumps.

The object of our invention is to provide a bellows or air-pump withimproved valve-seats and discharge-nozzle, by means of which air isreadily admitted into the bellows and discharged at the nozzle withoutleakage at the valves; also, the discharge end of the nozzle is adaptedto be removed when burned or otherwise damaged and a new one substitutedtherefor; also, to permit the bellows to be located at any desiredplace, and the nozzle eX- tended, without interfering with the steadydischarge of compressed air.

Our invention consists, mainly, in the new construction and arrangementof the valveseats and the nozzle-head; also, in the new combination ofelements, all of which are deemed essential in our newly-organizedbellows or air-pump, whereby new and useful results are produced, aswill be hereinafter fully described in the specification, and set forthin the claims.

In the accompanying drawings, in which like letters of reference inthe'different gures indicate like parts, Figure 1 represents aperspective view of our improved bellows or airpump. Fig. 2 isalongitudinal sectional view of thesame, taken vertically through thecenter. Fig. 3 is an enlarged view of the middle valve and aportion ofthe central partition and Fi g. 4: is a cross-section of the lower sideof the bellows, taken through the center of the inletvalves.

Referring now to the drawings, A represents the upper, and B the lower,side of the bellows. P represents the nozzle-head; E, the outer coveringof leather; b b', the partition with air-holes a a; M, the centralpartition; J K L, the nozzle; f f', the valves; w fw, the valve-seats G,the rear supportin g-bar; D D',

the handles; m, a, B', and (l, the cleats; g, the air-passage in thecentral partition, and g g' inlet air-openings in the bottom of thebellows.

The general construction of the bellows is similar to that of theordinary kind,.except the valve-seats, the nozzle, the nozzle-head, andthe location ofthe supporting-bar Gr. The head l? is made solid fromthree or more pieces of wood. rIhus the front end ofthe centralpartition, M, forms a central portion of the head, and isv built up onboth sides, the upper part having a hole in it to receive the nozzle J,and all firmly secured together by the band H. The nozzle is formedtapering or conical, as shown, and composed of three pieces-to wit, thepart J, which is secured in the head, the conical end piece, K, and thecoupling L. rI he end piece, K, is designed to be removed from the pieceJ when it becomes burned or otherwise damaged and a new piecesubstituted.

Should it be desired to locate the bellows at a distance from a furnaceor other device to which the compressed air is to be applied, the end Kis removed,- and a connecting-pipe of the desired length screwed orcoupled onto the piece J, and the nozzle K screwed or attached to theother end of the connecting-pipe.

The upper and lower sides of the head1 are united to the top and bottomA B of the bellows by leather hinges, in the usual manner, the cleats mand a, above and below, holding the hinges firm. rIhe leather sides ofthe bellows are secured to the top and bottom A B and to the partitionsM b b', and the leather is worked at the sides, so as to fold outward asthe instrument is closed up, while at the rear end of the bellows theleather is worked so as to fold inward, thus preventing the lifting-rod(not shown) that is attached to the handle D from rubbing and wearingout the leather at the end.

The supporting-bar Gr is located near the rear end ofl the bellows andfirmly secured on top of the central partition, M, thereby giving abetter support to the bellows.

rlhe partition M is provided with a square opening, g, above, all aroundwhich are securely glued strips of fur, w, with the hair aboveb Thevalve f is ot' the ordinary kind, made of leather, and is securelyfastened at r to the top of the partition M and to the bar G, as shownin Figs. 2 and 3.

The inlet-openings g g in the bottom B are each provided withvalve-seats made of fur, in the same manner as the one in the partitionM. The valves j" f are secured to the top orn the bottom B, an dprevented from rising too high by the flexible band t, which extendsacross both valves, and is secured to the bottom B at each side of theopenings g g', as shown in Fig. 4. The cleats B Gare designed tostrengthen the top and prevent it from splitting.

It will he seen from the foregoing that the valves ff f have seats infur, and that they make no noise in opening or closing when the bellowsare operated, which is very annoying in the ordinary bellows; also, thatwhen the valves are closed the joints are more perfect and less liableto leak than those of the ordinary construction; also, that the head Prequires no covering, and is perfectly tight 5 also, that the nozzle canbe removed when damaged, and a new one substituted, which is oi' greatimportance, especially when the nozzle is used in close proximity to atuyerc-iron.

Having thus described our invention, what we claim as new, and desire tosecure by Letl. In a bellows or air-pump, the fur valveseats w, as andfor the purpose specified.

2. The air-passages g g', having strips of fur, w, secured around theirupper edges, combined with the valves f, as and for the purposespecified. v

3. The solid head P, formed from three or more pieces oi' wood, andfirmly secured together by the band H, combined with the nozzle J K L,as and for the purpose specified.

4. In combination with a bellows, the crossbar G, said bar being locatednear the rear end of the bellows, as and for the purpose specified.

1n testimony whereof we have signed our names to this specification inthe presence of two subscribing Witnesses.
